FITNIR MC
Delivering accurate and reliable moisture content measurements for control strategy integrationFITNIR MC utilizes NIR spectroscopy to deliver accurate and reliable moisture content measurements of wood chips to the digester or hog fuel to the power boiler for control strategy integration. FITNIR MC’s high-quality and timely data provides clarity of feedstock properties that are essential for cost savings and process optimization.
Implementing FITNIR MC in conjunction with the control strategy suggests an overall increase in production of 2.5%, increasing mill revenue by an estimated $3.5 million per year. Eliminating large swings in the dry chip feedrate is expected to improve overall digester operation and reduce pulp quality variability by providing more consistent control of chemical dosing and vessel hydraulic loading.
